The FT4 is a clone of FT3: we find the same construction so "Land Rover" from the previous model, no external change is denoted aside a red stripe in the middle of the handle, without practical impact. We invite you to read the grip test of the Panasonic Lumix FT3. Summarizing: the gripping device remains correct, especially with lightly rounded handle, even if the zoom lever on the back makes it less enjoyable exercise.
